hello i am having problem described below. please try to help I am using DSK C6713 and CCS(v2.21).I want to use DSP library.This is a brief description of the problem: 1) I have downloaded SPRA121 and installed dsplib for c67x into my directory 'c:\' 2) I want to use dspf_sp_cfftr4_dif for radix-4 FFT. So, in my c file I added: #include "C:\CCStudio\c6700\dsplib\include\dspf_sp_cfftr4_dif.h" 3) Then added file dsp67x.lib to my project. 4) When I tried to build & link(tried using text as well as visual linker) the project,the following error come: ERROR illegal relocation type 050002 found in section .debug_info, file C:\CCStudio\c6700\dsplib\lib\dsp67x.lib. Please find attached the test project with this mail. A folder having dsp67x.lib and the dspf_sp_cfftr4_dif.h is also attached. -- Bhole Ka Bhagwan Chandresh Dubey 09891020212
